Page 9: Safety And Important Warning Items
Because of possible hazards to an inexperienced person servicing this copier as well as the risk of damage to the copier, Konica Minolta Business Technologies, INC. (hereafter called the KMBT) strongly recommends that all servicing be performed only by KMBT-trained service technicians.
Page 10: Safety Warnings
MODIFICATIONS NOT AUTHORIZED BY KONICA MINOLTA BUSINESS TECHNOLOGIES, INC. Konica Minolta brand copiers are renowned for their high reliability. This reliability is achieved through high-qual- ity design and a solid service network. Copier design is a highly complicated and delicate process where numerous mechanical, physical, and electrical aspects have to be taken into consideration, with the aim of arriving at proper tolerances and safety factors.
Page 11 CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE Konica Minolta brand copiers are extensively tested before shipping, to ensure that all applicable safety stan- dards are met, in order to protect the customer and customer engineer (hereafter called the CE) from the risk of injury.
Page 12 SAFETY AND IMPORTANT WARNING ITEMS WARNING: Power Plug and Cord • Do not bundle or tie the power cord. Overheating may occur there, leading to a risk of fire. • Check whether dust is collected around the power plug and wall outlet. Using the power plug and wall outlet without removing dust may result in fire.
Page 13 SAFETY AND IMPORTANT WARNING ITEMS WARNING: Ground Lead • Pay attention to the point to which the ground lead is connected. Connecting the ground lead to an improper point such as the points listed below results in a risk of explosion and electric shock: a.
Page 14 SAFETY AND IMPORTANT WARNING ITEMS CAUTION: Ventilation • The copier generates ozone gas during operation, but it is not sufficient to be harmful to the human body. If a bad smell of ozone is present in the following cases, ventilate the room.
Page 15 SAFETY AND IMPORTANT WARNING ITEMS DANGER: Work Performed with the Copier Powered • Take every care when servicing with the external cover detached. High-voltage exists around the drum unit. A risk of electric shock exists. WARNING: Safety Checkpoints • Check the exterior and frame for edges, burrs, and other damages. The user or CE may be injured.
Page 16 SAFETY AND IMPORTANT WARNING ITEMS WARNING: Safety Checkpoints • After replacing a part to which AC voltage is applied (e.g., optical lamp and fixing lamp), be sure to check the installation state. A risk of fire exists. • Check the interlock switch and actuator for loosening and check whether the interlock functions properly.
Page 17 SAFETY AND IMPORTANT WARNING ITEMS DANGER : HANDLING OF SERVICE MATERIALS • Unplug the power cord from the wall outlet. Drum cleaner (isopropyl alcohol) and roller cleaner (acetone-based) are highly flammable and must be handled with care. A risk of fire exists. •...

SCANNER SECTION Operation 1.2.1 Initial operation when power is turned on and shading correction reading When the SW2 (Sub power switch) comes on, the exposure unit starts a home position search. At this time, the exposure unit uses the white reference plate attached on the back side of the original pressing board for shading correction.

Page 52: Original Read Control
SCANNER SECTION 1.2.3 Original read control The light from the exposure lamp reflects back from the original, passes through a lens, and hits the CCD sensor. The CCD sensor generates an electric signal (analog signal) corresponding to the light intensity. Then, according to the instruction from the SCB (System control board), the ADB (A/D conversion board) converts this signal into a digital signal.

PAPER FEED UNIT 6.2.4 Paper size detection The paper size in the tray is detected by the CB (Main body control board), using signals sent from the PFDB/U (Paper feed detection board/U) and the PFDB/L (Paper feed detection board/L). The paper size in the tray is set by the SW1 of the PFDB/U and the PFDB/L, and the CB detects a switch signal according to the position of the SW1.

Page 171: Safety And Important Warning Items
Because of possible hazards to an inexperienced person servicing this copier as well as the risk of damage to the copier, Konica Minolta Business Technologies, INC. (hereafter called the KMBT) strongly recommends that all servicing be performed only by KMBT-trained service technicians.
Page 172: Safety Warnings
MODIFICATIONS NOT AUTHORIZED BY KONICA MINOLTA BUSINESS TECHNOLOGIES, INC. Konica Minolta brand copiers are renowned for their high reliability. This reliability is achieved through high-qual- ity design and a solid service network. Copier design is a highly complicated and delicate process where numerous mechanical, physical, and electrical aspects have to be taken into consideration, with the aim of arriving at proper tolerances and safety factors.
Page 173 CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE Konica Minolta brand copiers are extensively tested before shipping, to ensure that all applicable safety stan- dards are met, in order to protect the customer and customer engineer (hereafter called the CE) from the risk of injury.
Page 174 SAFETY AND IMPORTANT WARNING ITEMS WARNING: Power Plug and Cord • Do not bundle or tie the power cord. Overheating may occur there, leading to a risk of fire. • Check whether dust is collected around the power plug and wall outlet. Using the power plug and wall outlet without removing dust may result in fire.
